The solenoid valve with non-return valve incorporated is designed commercial coolers to replace a solenoid valve on the liquid line in parallel to a non-return valve for the reversal of the cycle. This valve can be used in the liquid line of exhibitors of supermarkets for the seal during the stopping phase, while allowing the full flow of refrigerant in the reverse direction, during hot gas defrost. It can also be used in the liquid line of a heat pump to prevent the migration of refrigerant to the outdoor condenser during the heating phase, while allowing the full flow of the refrigerant when flowing in the opposite direction commercial coolers in the cooling phase. Note: Reverse Flow / cooling cycle, the valve closes. Maximum operating pressure - Valves Series E42 - 31 bar, for all other models - 34.5 bar.
The three-way valves for Sporlan Heat Recovery have hermetically sealed in synthetic commercial coolers materials, specifically designed for switching the passage of the hot gas from the condenser to the normal recovery. Operation Type "B" Normal Capacitor (External) - De-energized - With the pilot valve de-energized, the discharge pressure can not enter the assembly of the upper cavity sealing piston. At the same time the pilot has the upper open passage to the suction pressure. The resulting pressure differential on the piston, pushes the piston seal in the closure of the passage of the recovery condenser (top). commercial coolers When the pilot valve opens, the cavity above the piston opens on the intake. The emptying of the recovery condenser is controlled by the calibrated hole on the piston. After the recovery condenser was emptied, and the valve continues to work on the capacitor normal all flows cease, thus eliminating the transition from high to low and the consequent loss of capacity. commercial coolers Type "C" Normal Capacitor (External) - De-energized - With the pilot de-energized, the discharge pressure can not enter into the cavity above the assembly piston seal. At the same time the upper part of the rider is open on the suction pressure. The resulting differential pressure, leads to the set-sealing piston commercial coolers to close the main passage of the recovery condenser (upper). The piston does not bleed prevents communication between the pressure side and suction operation with only normal capacitor. Type "B" commercial coolers and "C" capacitor Recovery (Heating) - Energized - When the pilot valve is energized, the discharge pressure can pass to the lower part of the pilot. At the same time the upper part of the pilot passage is closed on the suction side. The discharge pressure pushes on the top of the piston and moves the piston-seal together to close the passage on the capacitor normal and open the passage of the recovery. With the passage upper closed there is no communication with the suction and discharge system that operates at the recovery. Systems for Heat Recovery with pressure regulator outlet, double condenser with non-return valve incorporated When using a heat exchanger in a refrigeration system, the addition of a pressure regulator flow is important not only to maintain commercial coolers the pressure of the liquid at the entrance of the valve, but also to ensure the availability of a good hot gas to the heat recovery exchanger. Valves on the condenser double are important to minimize the demand for refrigerant commercial coolers in the winter. 3-way valves with non-return valve Integrated are important commercial coolers to minimize the costs of installation.
The valves for hot gas defrost are used in systems in which one or more compressors feeding different refrigerated exhibitors both medium and low temperatures. The 3-way valves are used to control the flow of gas from the outlet manifold to the various refrigerated exhibitors (defrost) or suction gas from the refrigerated exhibitors to the intake commercial coolers manifold commercial coolers (refrigeration). The direction of flow depends on the fact that the coil of the pilot valve is energized or de-energized. These valves 3-Vie are only used for hot gas defrost. When the coil is de-energized the valve allows the passage of the refrigerant in the normal direction of refrigeration. When the coil is energized the piston and its housing seat of the valve, switch, close the door and open the suction inlet port of the gas flow, allowing the hot gas to pass from the outlet manifold through the valve, to 'output dell'evaporator
